nyczoning.ai

nyczoning.ai

By NYC Zoning AI

NYC Zoning AI exposes read-only NYC zoning tools over MCP. Given a 10-digit Borough-Block-Lot (BBL), Claude can retrieve property and district context, computed zoning parameters (FAR, height limits, yards, use groups, overlays), MapPLUTO-derived lot geometry, and deterministic 3D zoning envelope parameters. Results include a link to the full interactive report on nyczoning.ai. Tools: • look_up_property_by_bbl — address, districts, ADU eligibility, listing metadata • get_zoning_info_by_bbl — computed zoning parameters (geometry omitted) • get_lot_geometry — lot outline and street GeoJSON • get_massing_envelope — setbacks, yards, height, and bulk envelope fields (computed geometry, not AI imagery) • list_properties — paginated property index by ZIP or borough Inputs are validated BBLs. Responses are capped and paginated. Authless public zoning data; full reports and downloads remain on nyczoning.ai.

oJo

oJo

By oJo

oJo renders documents from HTML templates. Claude writes or picks a template, fills it with your data, and oJo returns a hosted PDF or PNG link: an invoice, a receipt, a certificate, a report, an event ticket, a packing slip or an Open Graph card. Templates are saved in your oJo account, so the same layout fills with new data every time, from Claude, from your own code through the REST API, or in the oJo editor. Rendering is deterministic: oJo prints your HTML and CSS in a headless Chromium. It does not use an AI model to create images. PDFs follow the CSS @page rule for size and margins. Tools: list, get, create and update templates, render a template or raw HTML to PDF or PNG, and create a preview link to check a template in the browser before saving it. Each render uses credits from your oJo plan. Sign in with your oJo account when you connect.

odo.tax

odo.tax

By Odo Labs LLC

ohdear.app

ohdear.app

By Oh Dear

Oh Dear watches your websites so you don't hear about downtime from your clients first. This connector puts that data, and the settings behind it, in the conversation. Ask about what's happening right now: which monitors have issues, how much downtime a site had last month, when a certificate expires, which links are broken, whether a scheduled task failed to check in, what changed in DNS, how Lighthouse scores are trending, or what your application health checks are reporting. Then act on it. Create and update monitors, schedule maintenance windows or start one right now before a deploy, snooze a noisy check, post an incident update to your status page, and change where alerts go at team, tag or monitor level. Read access is always granted. Write access is opt-in, and you choose it on the consent screen along with which teams to share. You can narrow a connection to specific monitors or status pages, and revoke it at any time from Connected AI assistants in your Oh Dear account. Requires an Oh Dear account. Connecting is one OAuth approval, with no API key to copy and paste. Docs: https://ohdear.app/docs/tools-and-sdks/mcp-server

okrdev

okrdev

By Alexander Ashley Chisholm

okrdev turns OKRs into markdown files in your own repository and puts an AI coach beside them. The coach checks new work against your key results before it starts, pre-drafts the weekly check-in from git history and merged pull requests, and parks distractions instead of letting them become this week's work. It installs on an adoption ladder and never installs a level you did not ask for. Level 0 is a parking lot and takes ten minutes. Level 1 adds a mission, cycle objectives, check-ins and a scored retro. Level 2 adds collaboration rails for teams shipping through pull requests. The coach never blocks. It classifies, it argues, and when you overrule it, it logs the judgment call with your reason so the next planning session has a record instead of a memory. No MCP servers, no telemetry, no account, no network calls of its own. Everything it produces is a file in your repository, under your git history and your access control. Delete the okrdev directory and the marked block in your agent instructions file, and it never existed.

olachill

By MIA Co., Ltd. (OlaChill)

This connector lets Claude search that catalogue in 12 languages and return product names, the type of product, a "from" price in yen and the page where the traveller books. Every tool is read-only except one: when the traveller asks, it sends a charter coach quotation request to OlaChill (name, email and phone are passed only then). It never books or takes payment. Dates, live availability, the final price and cancellation terms are always shown on the product page on olachill.com.

opensignup.org

opensignup.org

By OpenSignup

OpenSignup makes ad-free, open-source sign-up sheets for snack rotas, potlucks, volunteer shifts, carpools, and anything else where people pick a slot. Participants click a link, choose a slot, and they're done. They never create an account. With this connector, you describe what you need and Claude builds it: - Set up a whole signup in one request: "Build me a snack rota for six Saturday games starting 3 October, two families per game." - Change it as plans change: add, edit, reorder, or remove slots and fields, and set how many people each slot needs. - Update the title, description, or closing time, and turn reminder emails on or off. - Publish when you're ready, then close, archive, or delete when you're done. - See all your signups and how full each slot is. New signups start as drafts that participants can't see. Claude gives you a preview link to check its work and an edit link to change anything yourself, then the public link to share once you publish. Claude can't see who signed up: participant names and emails aren't shared with it. Disconnect at any time from Connected apps in your account settings. Free to use at opensignup.org.

opionate.com

opionate.com

By Opionate

Opionate is a survey design and research platform. This connector lets Claude create and edit your own survey drafts directly in your Opionate account - add and reorder questions, set up display logic, and iterate on wording, all through conversation instead of clicking through a builder one field at a time. Every change is validated against the same rules Opionate's own survey builder enforces, and recent AI-made edits can be undone if a change doesn't work out. This connector is scoped narrowly on purpose: it can create and edit draft surveys only. It cannot publish a survey, launch respondent recruitment, or read responses, dashboards, or any other account data - and it can never see or touch a survey it didn't create or that isn't yours. Requires a free or paid Opionate account (opionate.com). Sign in and authorize once; after that, just describe the survey you want and keep refining it in conversation.

optimo

optimo

By Optimo IoT

Optimo IoT is a cloud platform for monitoring industrial assets: gateways installed on-site collect data from PLCs, meters and sensors (Modbus, Siemens S7, LoRaWAN, Node-RED and more) and stream it to the cloud, where it is visualised, aggregated and turned into reports and alarms. This connector gives Claude read access to that data, so you can ask questions in plain language instead of building a dashboard or querying the HTTP API: - Browse the asset tree and see how plants, lines and machines are organised - List and search the variables available on any asset, with their units - Read the latest value of a variable, or its raw history over a time range - Read aggregated history (averages, min/max, totals, counters) over a time range, for one variable or many at once - Read AIMS asset logs: the maintenance events reported against an asset in Optimo IoT's CMMS Typical uses: compare energy consumption across machines or shifts, investigate a production stop by correlating timeseries with maintenance events, summarise downtime, or pull figures for a weekly report. Access is authorised via OAuth against your cloud.optimoiot.it account, and you only see the assets your account already has permission to view. The server is read-only: it cannot change configuration or write data to the platform.

ovilloMCP

ovilloMCP

By Ovillo.lat

Ovillo is an execution and control platform for startups and scaleups: goals, initiatives, tasks, incidents, documents, time tracking and reporting in one place. This connector lets Claude work directly on the Ovillo spaces the connecting user can already access. Claude can list and search tasks across spaces, see what is assigned to the user and what is due or overdue, read a space's goals, documents, comments and text attachments, and pull a space's metrics. With write access it can create and update tasks and goals, create spaces, write and edit documents, comment on a task, ask a ticket's reporter for missing information, and log hours worked. The point is turning a conversation into tracked work: the plan Claude just wrote becomes real Ovillo tasks with owners and dates, instead of a document nobody revisits. Authorization is the user's own. Every call runs under the connecting user's permissions and is re-checked server-side per request: a space the user cannot see in Ovillo is invisible to Claude too, and a user who cannot write anywhere is not offered the write tools at all. The connector never exposes raw database access — only the 24 purpose-built tools, each annotated as read-only or write so Claude can ask for confirmation before anything changes. Access can be revoked at any time from Settings → Connections → Connected AI apps in Ovillo. An Ovillo account is required; the free plan is enough to try it.

pagegoat mcp server

pagegoat mcp server

By pagegoat

pagegoat turns an HTML page into a link you control, without leaving the conversation. Ask Claude to put a report, dashboard, prototype or any page it has written online, and it hands back a live URL at pagegoat.com/sites/your-name. New pages are private until you say otherwise. Once a page is up, Claude can: • Update it in place — new contents, title or address — while comments and access settings stay. • Change who can open it: public, password-protected, or only the people you name. • List your pages, show one page's settings, delete a page, and check your plan and remaining storage. What's different: access is checked on the server before the page is sent, so a locked page stays locked. People you share with can leave comments pinned to the exact words they mean. In the pagegoat web app you can also ask each visitor to confirm their email before the page opens. Sign-in is OAuth, so no API key is ever pasted into a chat. Creating pages needs a paid pagegoat plan, from $2.99/month. Viewing, listing and managing pages shared with you works on a free account.

pagent.ai

By aihumin GmbH

pagent is an AI agent for A/B testing, personalization and conversion rate optimization on your website. Ask Claude for an experiment and pagent writes the hypothesis, builds the variation as real code on your design system, and runs it as a controlled A/B test on your live site with Bayesian statistics. Every personalization runs against a control on a primary metric, so you can tell what actually lifted the conversion rate. Winners become the new baseline and shape the next hypothesis. From Claude you can list running and completed split tests, read their results in plain language, compare variations, and see what each one changes on the page. With write access you can capture a hypothesis, turn it into a test, start, pause, stop or roll one back, and manage pages, audiences and conversion goals. Built for CRO, growth and experimentation teams who want more tests than their design and engineering capacity allows. Your team reviews each variation before it goes live. One script tag on your site, no developer ticket per test.

paidfor

paidfor

By Sarmad Siddiqui

paidfor is an index of x402 sellers built by paying them. It buys their endpoints with USDC on Base, checks what was delivered, and records every failure: no delivery after payment, a quote above the listed price, a changed pay-to address, or a malformed response. The connector reads that public index. It has three read-only tools: check_x402_seller: pass an x402 resource URL or a seller domain and get a verdict (avoid, caution, ok or unknown), one sentence explaining it, the seller's paid-call count and failure rate with a 95% interval, the listed price, typical quote and largest overcharge when known, and links to the seller page and raw evidence. list_reliable_sellers: sellers with zero failures across at least 30 paid calls, optionally by category (inference, data, scraping, compute, other). recent_changes: what changed in the index, newest first: verdict changes, new failures, moved quotes, changed pay-to addresses and seller replies, for one seller or all. The connector never pays, holds no wallet, and needs no account or key. It sends only the URL or domain being checked. Methodology and raw data are public at paidfor.dev.
